This retrieves the latitude portion of the WGS84 coordinates of where the media was seized. This corresponds to the [Latitude] column of the [Media] table.

Syntax

double truxton_media_get_latitude( uint64_t media_handle );

Parameters

media_handle

The handle created by the truxton_media_open_id or truxton_media_create call.

Return value

The latitude portion of the geographic coordinate using the WGS84 ellipsoid of where this media was seized.

Sample

void has_location( uint64_t media )
{
   double latitude = truxton_media_get_latitude( media );
   double longitude = truxton_media_get_longitude( media );

   if ( latitude != 0.0 && longitude != 0.0 )
   {
      printf( "The media was seized somewhere\n" );
   }
   else
   {
      printf( "We don't know where this media came from\n" );
   }
}
